4K for me as a developer means that I can have a couple of source files and a browser with the API documentation open at the same time. I reckon I could use legitimately use an 8K screen - get a terminal window or two open as well, keep an eye on builds and deployments while I’m working on a ticket.
Now yes - gaming and watching video at 8K. That’s phenomenally niche, and very much a case of diminishing returns. But some of us have to work for a living as well, alas, and would like them pixels.
The app that you’ve always wanted, or at least, close enough so that you can tweak it and maybe submit a PR! Except of course that it’s written in .NET and uses WinForms for its UI. Bastards.
In some ways, I’m a bit envious of Windows for having a standardised UI toolkit, even if it’s terrible. Linux has a selection that are each flawed in their own way. I think the last time I enjoyed writing UI code was on the Amiga 1200, and that wasn’t yesterday.
